WILLIAM T. SCOTT, OF PARKERSBURG, IOW'A.

LOADING APPARATUS.

Application-filed June '11, 1909.

To all whom it may concern:

Be it known that- I, lVlLLIAM T. Soon, a citizen of the United States,residing at Parkersburg, in the county of Butler and State of Iowa, haveinvented certain new and useful Improvements in Loadin Apparatus; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in loading apparatus.

()ne object of the invention is to provide an apparatus of thischaracter by means of which manure, hay, sand, and other material may beelevated and lowered into or out of a wagon.

Another object is to provide an improved construction of grappling fork,having an improved tripping and load releasing mechanism, and havingmeans whereby the aws of the same may be quickly converted into scoopsto enable the fork to lift sand, dirt, and similar material.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claim.

in the accompanying drawings: Figure 1, is a perspective view of loadingapparatus constructed in accordance with the invention. Fig. 2, is a topplan view of the grappling fork, showing the jaws in closed position.Fig. 3, is a cross sectional view of the same on the line 33, of Fig. 2.Fig. 1, is a similar view showing the jaws in open position; and, Fig.5, is a perspective View of the fork, showing the jaws in open positionand equipped with scoop plates, and Fig. 6 is a detail fragmentarysectional view showing a portion of one of the teeth of the grapplingfork and one of the scoop plates in section.

Referring more particularly to the drawings, 1., denotes the base plateof the apparatus, and 2, denotes the mast, the lower end of which isrevolubly mounted in a step bearing formed in said base plate, wherebysait. mast may be freely turned to swing the load to the desiredposition. The mast is held in position by inclined brace bars 3, thelower ends of which are secured to the base plate 1, and the upper endsto a supporting Specification of Letters Patent.

ring t, which is arranged on and loosely engages the mast 2, adjacent toits upper end, as shown. The mast may also be further supported by a guyrope 5, the end of which has a swiveled connection with the upper end ofthe mast. The upper end of the mast recessed. or slotted and in saidslotted end is revolubly mounted a guide pulley 6.

Slidably mounted on the mast 2, is a boom 7, said boom being preferablyloosely connected at its inner end with the mast by a suitable clip 8.In the outer end of the boom are arranged two guide pulleys 9, betweenwhich and engaging the guide pulley 6, in the upper end of the mast is ahoisting rope or cable 10, said rope extending down from the pulley 6,along side the mast and through a guide pulley 11, secured theretoadjacent to its lower end. From the pulley 11, the hoisting rope ispassed once or twice around a drum or pulley 12, which is mounted insuitable bearings 13, arranged on the base plate 1, and from the pulleyor drum 12, the rope extends a suitable dis tance from the hoistingapparatus and is connected to a suitable draft device, by means of whichdraft animals are hitched thereto to raise the load connected to theopposite end of the hoisting rope or cable. Connected to the boom, nearits inner end, is a raising rope or cable 14, and to the boom adjacentto its outer end is connected a similar rope or cable 15. The cables Itand '15, pass over a guide pulley 16, secured to the mast and fromthence extend downwardly and are adapted to be secured to a cleat 16,arranged on the mast adjacent to its lower end. By means of the rope orcable 1 1, the boom may be raised bodily on the mast to any desiredelevation, while by means of the rope or cable 15, the outer end of theboom may be swung upwardly to any desired angle. To the boom 7, is alsoconnected a cord 17 by means of which the boom may be swung around toany desired position.

Connected to the end of the hoisting rope, is a grappling fork 18, saidfork comprising a pair of jaws, each of which consists of a bar 19,which is preferably formed of metal and to the outer side of said barsare secured a series of curved teeth or tines 20, said tines beingsecured to the bars 19, by bolts 21, and clips 22. On the inner side ofthe bars 19, are arranged a series of bearing eyes 23, through which isinserted a pivot bolt or rod 24:, the ends of which are bent atright-angles or headed to prevent the dis engagement of the bolt or rodfrom the eye.

In the inner sides of the bars 19, adjacent to their lower edges areformed recesses in which are arranged eyes 25, to which are secured jawclosing and supporting cables 26, said cables being connected at theirupper ends to a hoisting ring 27, with which is adapted to be engaged ahoisting hook 28, which is secured to the end of the hoisting cable, asshown.

To the outer side of the bars 19, adjacent to their lower edges aresecured supporting and opening cables 29, said cables being connected attheir upper end to the lower end of the hoisting cable, as shown. Theopening and supporting cables 29, are of greater length than thecombined length of the hook 28, and the closing and supporting cables26, so that when said hook is engaged with the ring 27, the fork issupported by the cables 26. The connection of the lower ends of thecables 26, with the bars 19, of the fork, is such as when the hook 28 isengaged with the ring 27, the jaws of the fork will be drawn inwardly ortogether, thus grappling and securely holding the load between the same.

When the jaws have been engaged with the load and the hook 2S, engagedwith the ring 27, the hoisting cable is operated to draw the forkupwardly to the desired elevation and the boom is then swung around tothe desired position. IVhen the loaded fork has thus been brought to theproper position, the hook 28, is disengaged from the ring 27, by a triprope 30, which is connected to the hook 2S and passes through a guideeye 31, arranged in the boom. \Vhen the hook has thus been disengagedfrom the ring, the weight of the loaded fork will be thrown on theopening and supporting cables 29, which, owing to their manner ofconnection with the aws, will swing the latter upwardly to an openposition, thus dumping the load.

In connection with the tines or teeth of secured in any suitable manner.

the jaws of the fork, I provide scoop plates 32, which are preferablyformed of sheet metal and are curved to fit the curvature of the teeth20, to which they are detachably On the lower edges of the scoop platesare arranged V-shaped steel scraping blades 38, which engage and fitover the ends of the teeth or tines, thus facilitating the use of thefork for lifting or hoisting sand, dirt, or fine manure.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claim.

Having thus described my invention, what I claim is:

In combination, a grapple comprising a pair of pivotally connected bars,outwardly curved teeth secured to said bars, jaw supporting and closingcables connected with the inner and lower edges of said bars, asupporting ring for engaging the free ends of said cables, a hoistingcable a connecting hook connected with said hoisting cable and adaptedto engage said link to normally hold the jaws closed, opening cablesconnected with the outer faces of the bars of the grapple and with thehoisting cable, said opening cables adapted to support the weight of thegrapple when the hook is disconnect ed from said link, and releasingmeans for said hook.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
